AWS - API Call - jquery ajax error

I'm new to AWS. Trying to consume an API in AWS. It's an AJAX request, the response is something like {“readyState”:0,“responseText”:“”,“status”:0,“statusText”:“error”}

I'm trying to consume the API from my localhost. As few posts says AWS doesn't allow crossDomain request. How do I test it locally?

        var postURL= "http://example.com/user/" + txtMemberId;

        $.ajax({
            url: postURL,
            crossDomain: true,
            datatype: "text",
            success: function (data, textStatus, xhr) {
                console.log(data);
            },
            error: function (xhr, textStatus, errorThrown) {
                console.log(xhr);
            }
        });  

The status is a (ok=200) and it's a valid response if I directly hit the API by giving URL in the browser
